King Edward Memorial Park Foreshore T.1 Introduction T.1.1 In an average year, the North East Storm Relief Sewer combined sewer overflow (CSO) discharges approximately 782,000m3 of untreated sewage into the River Thames in front of King Edward Memorial Park in the London Borough of Tower Hamlets. The CSO discharges approximately 31 times a year and releases 200 tonnes of sewage derived litter. T.1.2 A worksite is required to connect the North East Storm Relief Sewer CSO to the main tunnel. The proposed development site is known as King Edward Memorial Park Foreshore, which is located in the London Borough of Tower Hamlets. The location of the site is illustrated in Annex T. T.1.3 This assessment is structured as follows: a. Section T.2 provides a brief description of the King Edward Memorial Park Foreshore site. b. Section T.3 sets out the planning context for works in this location. c. Section T.4 describes the site-specific development for which consent is sought and how the proposals evolved through consultation. d. Section T.5 analyses the principal site-specific planning considerations and how the proposals comply with relevant planning policy. e. Section T.6 provides an overall conclusion of the site-specific assessment for the proposed works at the site. T.2 Site description T.2.1 The proposed development site comprises the foreshore of the River Thames adjacent to King Edward Memorial Park and an area in the south of the park, including hard-surfaced sections of the Thames Path, an area of green space, and part of the multipurpose sports pitches to the west. An aerial photograph of the site is provided in Figure T.1 overleaf. T.2.2 The site is bounded by King Edward Memorial Park and The Highway to the north, the residential Free Trade Wharf building to the east, the River Thames to the south, and by the Shadwell Basin Outdoor Activity Centre and Glamis Road to the west. There is an existing jetty and decking in the river adjacent to the Free Trade Wharf to the east. T.2.3 The North East Storm Relief sewer runs beneath park in a southeasterly direction and discharges into the River Thames through the river wall. The CSO point is marked by three large openings in the river wall. The foreshore in this location is exposed when the tide is low, with a mean low water mark some 30m from the river wall. The River Thames in this location is characterised by a wide expanse of water, moored and passing vessels, and piers and structures situated in-river.

The presence of this road tunnel is marked by the ventilation building in the southern portion
